Comments and tips
The side push-up is an awkward exercise, with a short range of motion. Performing it properly takes practice. When performed properly, the exercise can effectively overload the lower pectoralis major. However, it’s not a recommended exercise. Use it occasionally to add variation to your workout.
Keep your core tight and your hips and torso straight. Do not flex your waist laterally. Your spine should be straight throughout the movement, and there should be a straight line from your shoulders to your knees.
